PORT OF SPAIN, Trinidad - Former Member of Parliament for Chaguanas West Jack Warner would face expulsion from the United Na­tional Congress (UNC) if he contests the by-election as an independent candidate. Prime Minister Kamla Persad-Bissessar yesterday said the party’s constitution does have certain sanctions and provisions that prevent a member from contesting a seat as an independent candidate. “The constitution of the party provides for what will happen if a person should go up on any other ticket except that of the party. I think the constitution provides that such a person would be expelled,” Persad-Bissessar said.
